Benefits of technology

This patent describes a vehicle system that uses a special gear mechanism to transmit power from electric motors to the wheels of a vehicle. This allows for independent suspension and control of each wheel, improving driving comfort and safety. The system also includes a torque sensor to detect the amount of power transmitted to the wheels. This vehicle system can improve power and efficiency in sports cars and other vehicles by adding an electric drive and energy storage system. The gear mechanism design increases the maximum torque produced at the wheels, allowing for a more powerful and responsive driving experience.

Problems solved by technology

The above-described chassis or axle designs disadvantageously relate to rigid portal axles.
Furthermore, electrical machines with coaxially arranged rotational axes do not permit any relevant change in length.

Embodiment Construction

[0031]The motor vehicle equipped with the chassis of the invention preferably is a car intended to be used in racing. The individually suspended wheels of the car that are associated with the rear axle are driven by an internal combustion engine. The wheels associated with the front axle also are individually suspended and can be driven by electric motor to apply an additional drive torque by means of the front wheels. The following description relates to the design of the motor vehicle in the region of the front axle and the chassis of the invention in this respect. This chassis 1 has an electrical axle 2 that is designed as a portal axle with two portal axle sections in the form of tubes that represent the housings 3 for accommodating two electrical machines 4. The housings 3 and the electrical machines 4 are arranged parallel and next to one another in relation to their rotation axes 5, with the spacing between the rotation axes 5, taking into account the outside diameter of the ...

Abstract

A chassis (1) for a motor vehicle has an electrical axle (2) with two electrical machines (4) for respectively driving two wheels (6). The chassis (1) also has a step-down gear mechanism (10, 11) arranged between the respective electrical machine and the associated wheel. Each step-down gear mechanism is connected to the respective wheel by a cardan shaft. The respective rotation axes (5, 5) of the two electrical machines are arranged parallel and next to one another. The chassis enables each wheel to be mounted in a non-rigid manner and permits the overall length of the electrical machines to be varied on account of the arrangement of the rotation axes of the electrical machines.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority under 35 USC 119 to German Patent Application No. 10 2010 010 438.8, filed on Feb. 26, 2010, the entire disclosure of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a chassis for a motor vehicle, having an electrical axle with two electrical machines and wheels rotatably mounted in the region of the two ends of the electrical axle. Each wheel to be driven by one of the electrical machines. A step-down gear mechanism is arranged between the respective electrical machine and the wheel associated with the electrical machine.[0004]2. Description of the Related Art[0005]DE 295 18 401 U1 discloses the above-described type of chassis used in a utility vehicle. This utility vehicle is a city bus for transporting people. A carriage floor is arranged at a low level of the city bus and runs through the entire bus, including the region ...
